Sure the Logitech Z-5500 speaker system looks like it's meant for your home theater, but it's actually one of the most powerful computer speaker systems you can get.

Snip:

"As of publication, Logitech has three 5.1 speaker options available: The budget-priced X-540, the gamer-targeted G51, and the home theater enthusiast-ready Z-5500. Just looking at the power rating is enough to give the reader an idea of where each lies in terms of the performance (and price) spectrum. The X-540 tops out at 70 watts, the G51 sports 155 watts, and the Z-5500 coyly flaunts its 505 watts or raw power. Of course, it’s worth mentioning that the low-end X-540 is the result of several revisions since the Z-5500 was introduced, and that the G51 is the latest addition to the family. This makes us suspicious that a refresh to the Z-5500 is in the works (though no details on rumored replacements have yet surfaced on our radar).

Anyways, the Z-5500 comes packed with four 62 watt satellite speakers, a 69 watt center channel unit and a 188 watt subwoofer. Each satellite driver measures 3”, with the subwoofer fitted with a 10” high-excursion ported driver. The THD is a disappointing-on-paper 10% which, although most home theater enthusiasts would scoff at that number and only consider <5% an acceptable range, in practice we found sound accuracy to be surprisingly excellent. All speakers run to the powered subwoofer, which is controlled by the wired remote. "
